Remarks on Semileptonic B and D Decays into Orbitally Excited Mesons [PDF]

, 2002
We have obtained the differential decay rate and calculated the branching ratios of the exclusive semileptonic decays $B(D) \to Xl\nu$, where $X$ is a p-wave meson, using the nonrelativistic ISGW quark model. Our results are compared with the predictions
